Benefits of technology

The present invention provides an in-vehicle input device that can be reliably operated regardless of the operator's finger or gloves, and can detect input operations accurately. The device uses a touch panel with a spacer and a suppression layer to prevent unintended finger motion during driving. The suppression layer reduces the formation of capacitance between the operator and the upper electrode, and allows for input operations to be detected based on a change in distance between the lower electrode and the upper electrode in response to pressing any of the operation areas. The device can be used while rotating the steering wheel, providing an input operation regardless of the steering wheel's operation state.

Problems solved by technology

If such a touch panel input device for a mobile apparatus is used for an in-vehicle apparatus, the input device may be erroneously operated in response to the motion of a driver driving a vehicle.
Unfortunately, an unintended operation may be performed, causing a safety problem.
In the operation device 900, however, any input operation cannot be performed while the driver rotates the steering wheel.
If the steering wheel is in the straight-ahead driving position, a likelihood that the touch panel may be erroneously operated will still remain because the driver may unconsciously move part of their body over the touch panel while driving, for example, while driving in a forward-leaning posture or while driving with one hand on upper part of the steering wheel.
Unfortunately, the touch panel cannot be operated.

first embodiment

Modification of First Embodiment

[0056]An exemplary configuration and operations of the in-vehicle input device 110 according to a modification of the first embodiment of the present invention will now be described with reference to FIGS. 2 and 5. FIG. 5 is an enlarged sectional view of part of the in-vehicle input device 110.

[0057]As illustrated in FIG. 2, the in-vehicle input device 110 includes two touch panels 18 mounted on the right and left of the central part 60a of the steering wheel 60 of the vehicle such that the touch panels 18 are adjacent to the wheel part 60b, or so that the operator can easily operate the in-vehicle input device 110.

[0058]The in-vehicle input device 110 differs from the in-vehicle input device 100 in that each touch panel 18 includes a contact member 19 as illustrated in FIG. 5. The in-vehicle input device 110 has the same configuration as that of the in-vehicle input device 100, except for the contact member 19. A description of the configuration excl...

second embodiment

[0067]An exemplary configuration and operations of the in-vehicle input device 200 according to the second embodiment of the present invention will now be described with reference to FIGS. 2, 6, 7A, and 7B. FIG. 6 is an enlarged plan view of part of the in-vehicle input device 200. FIGS. 7A and 7B are enlarged sectional views of parts of the in-vehicle input device 200. FIG. 7A is a sectional view of part including a first operation area 25b of the in-vehicle input device 200. FIG. 7B is a sectional view of part of the in-vehicle input device 200 in which the first operation area 25b is used as the first detecting unit and a second operation area 25c is used as the second detecting unit. FIG. 7A illustrates a section as viewed from the line VIIA-VIIA in FIG. 6. FIG. 7B illustrates a section as viewed from the line VIIB-VIIB in FIG. 6.

[0068]In the in-vehicle input device 200, the same components as those in the in-vehicle input device 100 are designated by the same reference numerals...

third embodiment

[0077]An exemplary configuration and operations of the in-vehicle input device 300 according to a third embodiment of the present invention will now be described with reference to FIGS. 2, 8, and 9. FIG. 8 is an enlarged plan view of part of the in-vehicle input device 300. FIG. 9 is an enlarged sectional view of part of the in-vehicle input device 300. FIG. 9 illustrates a section as viewed from the line IX-IX in FIG. 8.

[0078]In the in-vehicle input device 300, the same components as those in the in-vehicle input device 100 are designated by the same reference numerals. A detailed description of these components is omitted.

[0079]As illustrated in FIG. 2, the in-vehicle input device 300 includes two touch panels 30 mounted on the right and left of the central part 60a of the steering wheel 60 of the vehicle such that the touch panels 30 are adjacent to the wheel part 60b, or so that the operator can easily operate the in-vehicle input device 300.

Abstract

An in-vehicle input device includes a touch panel including a lower electrode, an upper electrode, and a spacer, and is capable of detecting a capacitance between the lower electrode and the upper electrode. The device has an operation surface located above the upper electrode. The operation surface includes a plurality of operation areas. The spacer has a plurality of openings that coincide with the operation areas in plan view. The device further includes a suppression layer that is disposed between the operation surface and the upper electrode or disposed on an upper surface of the operation surface. The suppression layer eliminates or reduces formation of a capacitance between the upper electrode and an operator. The device detects an input operation based on a change in distance between the lower electrode and the upper electrode in response to pressing any of the operation areas by the operator.

Description

CLAIM OF PRIORITY[0001]This application claims benefit of Japanese Patent Application No. 2015-115486 filed on Jun. 8, 2015, which is hereby incorporated by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to in-vehicle input devices, and in particular, relates to an in-vehicle input device that can be operated with a touch panel disposed on a steering wheel.[0004]2. Description of the Related Art[0005]In-vehicle input devices including touch panels instead of mechanical input units have recently been developed. Such an input device has a switch operation area disposed on a steering wheel to provide layout flexibility and a flat appearance. Touch panel input devices are widely used mainly for mobile apparatuses. Such a touch panel input device detects an input operation based on a change in capacitance caused when an operator operating a mobile apparatus moves their finger closer to an operation surface of the input device.[0006...
